To earn the ENERGY STAR, the Atlanta and Denver sites scored in the top 25 percent of similar facilities nationwide for energy efficiency, based on the U.S. Environmental Protection Agency''s (EPA) energy performance rating system, the release stated.

According to the release, qualified facilities meet strict energy performance standards, use less energy, are less expensive to operate and cause fewer greenhouse gas emissions than peer facilities.
